Swelling device with middle screen guide rod and for accelerating dissolution of polymer

Abstract

The invention discloses a swelling device with a middle screen guide rod and for accelerating dissolution of a polymer. The swelling device is characterized by consisting of a power system, a motion conversion system, a vibration source system and a container, wherein the power system is formed by connecting a motor and a driving wheel; the motion conversion system is composed of a beating rod, a contact head, a reset spring, the middle screen guide rod and a middle screen frame; the beating rod is arranged on the driving wheel; the contact head is fixed on the middle screen frame; the reset spring and the middle screen guide rod are arranged at the two sides of the middle screen fame; one end of the middle screen guide rod is provided with a bolt and sequentially penetrates through the middle screen frame and the reset spring to be fixed on the container; the middle screen frame and the reset spring can move on the middle screen guide rod; the vibration source system is composed of an end screen frame and a metal wire fixed on the end screen frame; and at the two ends of the end screen frame, the metal wire is tightened on the container through a pulling rope and an extension spring. The swelling device disclosed by the invention can shorten dissolve time of the polymer, reduce the size of equipment required to prepare the polymer, and reduce occupied space and weight on an offshore platform.

Description

technical field [0001] The patent of the present invention relates to a polymer dispensing process, in particular to a tenting device with an intermediate mesh guide rod for accelerating polymer dissolution. Background technique [0002] At present, the world mainly adopts gas injection and water injection for oil recovery, but due to the limitation of factors such as the lack of gas sources and the level of productivity in my country, water injection is mainly used for development in China. However, in the late stage of water injection development, the water cut increases and the crude oil production decreases. Chemical flooding has become a necessary stage for waterflood development of oilfields. Experts and scholars at home and abroad have conducted a large number of researches and field experiments, mainly including polymer flooding, surfactant flooding, polymer-surface binary system flooding and ASP flooding, etc. . Polymer flooding is the most widely used and most ma...

AI Technical Summary

Problems solved by technology

At present, the polymer preparation process in Daqing, Shengli and other oilfields takes a long time to dissolve the polymer, and the volume and area of ​​the device are large, so the polymer preparation process cannot be applied on offshore platforms.
